Question

我在我的应用中使用DrawerNavigator。我创建了一个Android应用程序，它与android 4.2完美配合，但当我尝试在Android 2.2中启动它时，我收到此错误：

android.view.InflateException: Binary XML file line #1: Error inflating class <unknown>

编辑：这些行也在那里：

07-22 16:00:52.111: E/AndroidRuntime(470): Caused by: android.content.res.Resources$NotFoundException: File res/color/abs__primary_text_holo_light.xml from xml type drawable resource ID #0x0

07-22 16:00:52.111: E/AndroidRuntime(470):  ... 42 more

我无法弄清楚原因。我从fragment打电话给我ShelrockFragment（MainActivity}：

FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.content_frame, newsMasterFragment, "MasterFragment");
        bundle.putBoolean("onFirstRow", true);
        newsMasterFragment.setArguments(bundle);

在充气视图时崩溃：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_news_master,
            container, false);

Answer 1

如果有人遇到同样的问题，则问题是android:background

android:background="?android:attr/activatedBackgroundIndicator"

粉碎整个应用程序。所以我在pre-Honeycomb版本中删除了它

Answer 2

这是因为片段API是在Android 3.0（API级别11）中引入的。

如果要在Android 2.2（API级别8）中使用它们，则必须使用Google提供的兼容性库。怎么做，你可以在这里阅读：Fragments in Android 2.2.1, 2.3, 2.0. Is this possible?

Answer 3

在drawer_list_item.xml文件中

删除android：background =“？android：attr / activatedBackgroundIndicator”line

如果你想用html颜色代码改变背景。

用抽屉导航错误类android 2.2
